: Application filed September My invention consists of an improvedmachine for ornamenting or brocading leather,

andhas for its particular object, the brocading of ooze or' suedeleather. j

In the accompanying drawing illustrating my invention Fig. 1 is a planview of my ma- "cylinder having the ornamental pattern or design to bereproduced, formed on the 'pe -riphery of the roll,,combined with otherstructural features to adapt ,it'to practical use. ,7 I 7 Referring tothe. drawing, 6. is theframe of the machine supporting suitable bearlngsin which are mounted the paper roll.7, the brocading cylinder 8, thepressure roll 9, the

"brush roll 10, the feed roll 11, and the carding roll 12. Thepaper'roll7 'is'adapted to carry asheet of paper 18, which paper has an adhesivecoating over the surface which is presented in contact with the suedeside of the leather while it is subjected to the action of the.brocading cylinder. 'The adhesive coating of the paper 1-3 consists ofany suitable gum, such for instance as shellac and alcohol preferablywith the addition 'of'some softer gum thinly and uniformly spread uponthe paper and dried, and containing, if dev V the hide or skin betweenthem, as other .fa-

- sired, some coloring matter or dye. V

I have discovered that thesuede side of leather will permanently retainav pattern transferred by a heated brocading roll through a gummedpaper, and lfthe gu'mmed paper is colored, a correspondingly coloredpattern is. permanently transferred thereby.

The gummed substance in the paper is driven into the texture of theleather at the points "of immediate contact of the'p'atternwiththebecomes indelibly impressed therein.

leather and thereby the pattern is more clear-' ly defined andpermanently sealed than when no'gummed substance '15 used. Furthermorewhena colored pattern is required, the gum, acts as an efficientconveyor'of the. coloring matter into the texture of'the leather andlitTie bestresults are produced by; employing a pressure roll with thebrocad ng roll; The

and the gum has no opportunity to spread, and blur the pattern, whichwould be the tenor platen were: used insteadofa roll,

' 'The paper roll'7 is mounted, asv shown supports at the top of theframe of the machine, and the sheetof paper 13 is fed] downwardlytherefromand underfthe brocading cylinder 8, together with the'leather,

the paper lying between the surfaceof the 3 f and the'upper or suedeb'rocading. cylinder 8 side of the leather. The brocading cylinder 8 ismounted in vertically and yieldingly. adjustable.; bear-.-

ings l t for the purpose of varying thespace between thebrocadingfcylinder 8 and the pressure jroll 9,150 as toadapt'it. todifferent thicknesses of leather and-forth'e purposeof regulating thedegree of pressure ofthe pattern or design uponthe surface oftheleather,

and to compensate for variationsin the thickness of a. given hide/orskin;;-

.I have shown as one form of means foryer tically and yieldinglyadjusting the pressure 1 of thebrocading. cylinder 8 the adjusting screw15, and the helical spring lfi interposed between the bearings 14 of thebrocading cylinder 8 and the cap 31 secured totheend of" the adjustingscrew 15. Both bearings of the brocading cylinder'8 are provided withsimilar vertically and yieldingly adjusting means.

My invention is not limited to the specific means shown for adjustingthe space between the broca'din'g cylinder 8' and the pressure roll 9,and for regulating the. pressure upon miliar and-well known m-eansofaccomplishing such adj u stment would be the equivalent of thecombination shown. It is-obvious also! that the arrangement may. bereversed by mounting thejbrocading cylinderki'n' fixed:

adjustable bearings...

Upon, the peripheral surfaceof the bro-v cading cylinder ,8 is formed orcut or arranged.

in any suitable manner the pattern or design to be reproduced upon theleather,v and. the pattern is of the cameotype, preferably cut aboutthree-sixteenths of an inch deep. The

depthof thepa-tternfmaybe varied to meet the special requirements inproducing different designs, and also to adaptit to the character and.weightof the leather -to .be br-o V Beneath the'brocading sub sure roll9 is mountedin iiXed bearings 32 in the frame of themachine, and betweenwhich and the brocading cylinder 8, the hide or skin 17 and the sheet ofpaper 13 are carried and the design upon the leather.

An important feature of my invention consists in constructingthepressure roll of less diameter than the brocading roll when the axeson which they are mounted are rotated atthe same speed. -The objectbeing to have I the surface of the pressure rolltravel at slightly lessspeed than the speed of the surfac'e'of the Y that by having thepressure roll of less d1 alnebrocading roll. I have discovered ter thanthe brocading roll by approximately the thickness ofthe material to bebrocaded, a much, clearer and more pronounced and permanent pattern isproduced upon the material. I

The tendency of this difieren'ce the speed of the. surface of thebrocading cylinder and thepressure rollis slightly to retard. the

I forward movement of thematerial. .Any

meansof adjusting the speed of the surface of roll slightly less thanthat of the pressure p the surface of the brocading rollto about theextent above described would be within the scope of my invention.

I have made application for United States 'Letters Patent jointly withJames Y; Lake for a'machine f or ornamentin'g leather, Serial-Number682,382, filedDecember 24, 1923, which is substantially the same as thema- 1 chine herein described, excepting thatin the machine of thepending applicationthe sur- [faces offthe brocading and pressure rollstravel atthe same speed.

on the front of the inachineis a table 18 over which the hide or skin 17is laid and from which it is fed between and by the feed roll 11, andthe brush roll 10 to the brocading cylinder '8 and pressure roll 9v asand for the purpose above described.

Thebrush roll 10 is useful in removing any dirt and foreign matter fromthe suede sur face of the leather, so that itjmaybe presentfed to. theaction of the brocading cylinder 8 to: the best advantagefor receivingthe impression of thepattern ordesign. The brush roll 10 is what itsname indicates,a roll havingvits periphery set-with-bristles of suitableroll 9.- I v 7 At the rear ofthe brocadingcylinder 8, and

length and stiffness-t0 adequately clean the surface of the hideor skin,and'to'cooperate.

with the feed roll 11 in presenting the-hide or skin to the brocadingcylinder '8 and pressure in contact with it, ismou'nted in suitablefixed bearings intheframe of the machine,thecarding roll 12.

The periphery ofithe carding roll 12 is cove I eredwith the well knownwire cardicloth com monly used in carding wool and othertextiles. Thecarding r0ll'12 is-rotated by means of ected to the required pressure toproduce 19, held in yielding contact'with the pressure roll 9, by meansof the adjustable bracket 20 secured to the frame of the machine, I -Forthe purpose of raising the'brocading cylinder 8, so as to insert thehide or skin and the sheet of paper 13 beneath it, or for any' otherpurpose temporarily to increase'the space between it and the pressureroll 9, I

have-provided a treadle connected by suit able vertical rods 33 with thelevers 34: pivot- 7 ed to the frame of the machine at35, the le-' vers34 being pivoted to the rod 36, Whichin turn is connected withthebearings 14 of the brocading roll 8. 1

The brocading cylinder 8 is, hollow and preferably is heatedelectrically by means of resistance coils installed within the cylinder.

The resistance coils are'preferably contained in a plurality of glasstubes 37 and are connected with a source ofpower through the wires 39and the brush 38 forming a contact in any of the well known ways. Thebrocadmg cylinder Sinay, however, be heated by a gas or oil flame or bysteam or any other suitable source of heat. The brocading cylinder 8,and of cou'rse the pattern upon it, should-ordinarily be heated to atemperature of from about two hundred to two-hundred fifty degreesFahrenheit during the operation" This, however, must depend of themachine. upon certain varying conditions, namely, the

thickness of the skin to be ornamented, the kind of dye used and thespeed of operation of the machine, which the operator must take intoconsideration in regulating the tempera ture'of the roll. 1

Mounted upon the shaft of the roll 9 is the driving pulley of themachine driven by abelt from anysuitablesource'of power. Thegear 21 (seeFig. 3) on the shaft of the pressure roll .9, drives thegear 22'on theshaft of'the brocading cylinder 8, which in t urn', through theintermediate gear 23, drives the gear 2 on the shaft of the "brush roll10,the gear-2d meshing with gear- 25'.

on the shaft of the feed roll 11, by which the latter is driven. a Thecarding roll 12 is driven by the gears 27and 21. v r

The brush roll10 is also mounted in vertically and yielding'lyadjustablebearings, .the

the gear 26'mounted on itsshaft, and by pressure I adjusting meansconsisting of the adjusting screws 28,and the helical springs 29-confined between the bearings 40 of the brush roll'10 and the plate 41secured to the adjusting screws28.

The operation of the machine is as follows: v

The brocading cylinder having attained the requisite degree of heat, asabove de-V scribed, a hide or skin is laid upon the table 18 withitssuede side upward, and is presented to the feed roll 11, whichdelivers it between the broc'ading cylinder 8 and the pressure roll 9.Simultaneously the sheet of gummed and colored paper 13'is presented tothe brocading cylinder 8, as shown in the drawing (Fig. 5), above and incontact with the suede side of the hide or skin, the sheet of paper 13and the hide or skin being fed together between the bro'cadin cylinder 8and pressure roll 9, under sufficient pressure to transfer the design ofthe pattern on the brocading cylinder 8 to the surface of the hide orskin. By reason of the pressure of the pattern upon the paper and theheat of the roll, the hide or skin will receive and permanently retainnot only the figure of the pat-- term-but the color of the guininedsurface of the sheet 18, so that by these means an accurate reproductionof any pattern or design in form and color may be obtained upon the oozeor suede side of the leather.

7 The chiefnovelty of this invention over the machine described in saidpending application, consists of the pressure roll being of lessdiameter than the pattern roll.

' My machine, by suitable adjustment of the pattern and pressure rolls,may be used for to travel at slightly greater speed than the V peripheryof the other roll.
